The best way to prevent 885º F embrittlement is to use low ________ alloys, or to avoid exposing the susceptible material to the embrittling range.
A) Austenite
B) Martensite
C) Ferrite
D) Chromium

Question

Quizplus · Accepted Answer

Low ferrite alloys are the best option to prevent 885º F embrittlement. This type of embrittlement occurs when ferrite grains become coarser, leading to a decrease in toughness and ductility. Using low ferrite alloys can prevent this by limiting the formation of coarse ferrite grains. Avoiding exposure to the embrittling range is also important, but may not always be possible in certain applications. Choices A and B are not correct because austenite and martensite are not directly related to the prevention of 885º F embrittlement. Choice D is not correct because while chromium can improve corrosion resistance, it is not directly related to preventing embrittlement.
